```							Let us start with 70% who lost one eye  Consider 80% lost one ear. This means 20% did not lose one ear.  Suppose this 20% all lost one eye as well.  This means 70% - 20% = 50% lose one eye and one leg  Consider 75% lost arm next.  This means 25% did not lose arm.  Suppose this 25% all lose one eye and one ear.  This means 50% - 25% = 25% lose ear, one eye and one arm  Consider 85% lost a leg  This means 15% did not lose leg.  Suppose this 15% all lose ear, one eye and one arm.  This means 25% - 15% = 10% lost all 4 limbs.  Now, it is given that x% lost all four limbs. So, x=10
